VLD25-SMT Series
300~700 mA Output, SMT, Constant Current Led Driver, Dc-Dc Converter

The VLD25 series is a step-down constant current dc-dc converter housed in a compact SMT package that has been designed for driving high power LEDs. Providing efficiency levels up to 96% and a wide input range, the series offers two means of LED dimming: PWM digital dimming control and analog dimming control via a trim POT. The VLD25 is ideal for LED applications where precise accuracy and brightness control is needed including signage, transport, consumer electronics, and signaling.
